Cativolcus
Cativolcus or Catuvolcus (died 53 BC) was king of half of the country of the Eburones, a people between the Meuse and Rhine rivers, united with Ambiorix, the other king, in the insurrection against the Romans in 54 BC; but when Julius Caesar in the next year proceeded to devastate the territories of the Eburones, Cativolcus, who was advanced in age and unable to endure the labours of war and flight, poisoned himself, after imprecating curses upon Ambiorix.
